Yeah but the mech engineer said. lol

Good for you. Just because it hasn't happened to you doesn't mean it can't happen.

I know how to use them also. They aren't that difficult.

I agree with this. One of my bikes has QR and disc. With the stock MT200 brakes it was fine. Once I upgraded to M6000 brakes, baking hard would cause the front wheel to shift in the left dropout. This was with (presumably) ****ty OEM skewers and once I switched to skewers that tighten with an allen key it aleiviated the problem. With that and QR being phased out on better bikes I wouldn't but a new bike with that configuration. I've already learned it significantly reduces aftermarket wheel options which will only get worse in the future.

Yup. For about $30 the problem is solvable.

At least you now admit that it's a problem.

Thru Axles for the Win!!!

Not much of a problem, really. I thought most reasonably serious cyclists know better than to run external cam quick releases.

In any case...QR will be a thing of the past except for department store bikes and entry level bikes.

Here is a page of Domane's. Exactly one bike (entry level) with QR and it has rim brakes. Rest are thru axle and disc.

On this, we agree! And I think that is a shame… Even around here, with lots of very steep hills, rim brakes are fine on a road bike, and - in some respects - are simpler and cheaper than discs.

Part of the safety benefit of a TA is that they are 99.9% fool proof.

QR is only 99% fool proof.

If you are in the top 1% of fools, then the difference matters.

When I need to stuff a bike into the hatchback I take the bike with QR and rim brakes.
No tools required and quick and easy especially when done multiple times during the day......

So you have multiple flats during a day?

The Trek Domane comes equipped with a lever that stays in the axle. No extra tools required to be carried.

Not flats but getting a bike into many cars or small SUVs requires removing the front wheel so the convenience of a qr is appreciated. Thru axles require specific fork holders for mounting on roof racks and some in-car and rear rack mounts but they are available.

Many TAs are tool free and just as fast as QR.

There is nothing more specific about TA racks compared to QR racks. A QR fork needs a QR rack and a TA fork needs a TA rack.

Not trying to question your preferences (personally, I am fine either way for road and gravel bikes), just wanted to point that out.

Yep, I know that but for someone new to thru axles, there may be other changes in the way they do things, like transport the bike on their car rack, and they should be aware of them. Actually I do prefer thru axles, particularly on a bike with disc brakes. The TAs on my Surly Midnight Special require a 5 mm allen key to remove and replace but that's not much of a burden and I will need a different fork holder when/if I want to carry it in my car.

Yeah, my Surly is the TA I have that does require a tool.
